Uninstall CHARM

To uninstall CHARM follow the directions given here. Files saved by CHARM will not be removed.

To see an example impact:

Start the program. A pair of tabbed dialogs will appear. For a new user, the
tabbed dialogs are the easiest method to enter a release and meteorological
description. To see the example results, it may be best to close the dialogs.
They can be reopened by selecting Description Dialog Input… or Met Dialog Input… in
the Options menu.

Flat terrain version (Charm9)–

Select Plume… in the Displays menu

Press the OK button on the dialog that appears.

Complex terrain version (Charm11) –

Select Open… in the File menu and open the file you find there

Select Open… in the Grid menu and open the file you find there

Select Open… in the MetFile menu and open the file you find there

Select Plume… in the Displays menu

Press the OK button on the dialog that appears.

If you become impatient, you can press Stop (show plume after next complete
time step) or Cancel (show plume from last complete time step).

Unlocking the CHARM Software

First, the program must be purchased. That can be done from the Home page.
The program is unlocked through the use of a License file supplied by us.
The License is created using unique identifiers for the machine upon which it
is to be run. The License is valid only for the machine that has those unique
identifiers. The license file must be placed in the directory where the appropriate CHARM.exe resides. Next time CHARM starts the file will be read. When the CHARM software is running the unique identifiers are available
on the dialog when CHARM starts or when About Charm, in the Help menu
is selected.

The unique identifiers can be sent to us manually by you or have CHARM send
it automatically. CHARM can send it automatically if you select Existing
User Get Key… in the Help menu. Fill out the form and press the Send button.

To send the information manually, you can note the unique identifiers, called
Site Code and Machine Identification (MID), and send it in an e-mail to Charm@CharmModel.com along with your name, company name, phone number, and e-mail address.

Each License file that will be returned when the identifiers are provided will be good only on the machine with those identifiers. They are not transferable to other machines. The identifiers for a machine are determined by its hardware configuration and some other factors. The identifiers may change if a machine is booted differently (e.g. to a different partition of the hard drive) or logged in to a different user. A different user may not see the same hard drive or RAM space.

Before you send the identifiers to us it is strongly recommended that the machine be in the configuration (boot and log in) that will be used when CHARM is to be run. Identifiers have changed in the past between initial installation (perhaps logged in as the administrator) and later when the final user is trying to use it.

Free Map Retriever

Maps can be an important feature in presenting the degree of impact from a release,
fire, or explosion. For the complex terrain version a map is often the first step
in creating a grid. CHARM does include an interface for downloading maps from Yahoo!®
via the Internet. Maps from Google™ and Bing Maps™ are not internally available due to use
restrictions in commercially available software. A program specifically designed to
retrieve maps from Yahoo!®, Google™, and Bing Maps™ has been developed.

After retrieving a map it can be saved in CHARM's format for immediate use. The map
is also loaded into the clipboard whenever a save is requested so that it can be
used in other programs.

The program can also be used to retrieve a map for an existing grid. When a grid file
is read its location and area coverage is used to determine the center point and zoom
level for a map.

The program, CHARMInetMaps.exe, is available for downloading without purchase or having to register.

Technical Descriptions

The technical description documents for both versions are available for download.
These documents are installed along with the program if the evaluation copies
are downloaded and installed.

Download the technical documentation for the flat terrain version here.

Non-CHARM Fun Stuff

These programs are just for fun or a waste of time, depending on your perspective.
They are provided with no support.

NWSData

This program is only for diehard meteorological data nuts. It allows you
to zoom into an area of the world. A region can be selected. The current
meteorological data for that region will be downloaded and displayed in standard
meteorological display format. The data can be analyzed to show isolines
for pressure, temperature, or dew point. Wind streamlines can also be shown.

Sudoku

This program allows you to solve a Sudoku puzzle. Enter the initial definition
of the problem or create a new game and save it. Then you select the other entries through the
use of drop down boxes. As you progress, the numbers available in each drop
down box is updated to only those that are possible. Hints and solving are available. Full undo of hints and your entries is present.
